java springboot+mybatis+oracle+web实现登入功能

好的，以下是一个简单的Java Spring Boot + Mybatis + Oracle + Web实现登录功能的示例：

1. 首先，创建一个Maven项目，添加以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.4</version>
</dependency>

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>19.7.0.0</version>
</dependency>

2. 配置application.properties文件，配置数据库连接信息

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//localhost:1521/orcl
spring.datasource.username=your_username
spring.datasource.password=your_password

3. 创建一个User实体类，用于存储用户信息

public class User {
    private Long id;
    private String username;
    private String password;
    // getter and setter
}

4. 创建一个UserMapper接口，用于定义CRUD操作

@Mapper
public interface UserMapper {
    @Select("SELECT * FROM users WHERE username = #{username}")
    User findByUsername(String username);
}

5. 创建一个UserService类，用于处理用户登录逻辑

@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;
    
    public User login(String username, String password) {
        User user = userMapper.findByUsername(username);
        if (user != null && user.getPassword().equals(password)) {
            return user;
        }
        return null;
    }
}

6. 创建一个UserController类，用于处理Web请求

@RestController
public class UserController {
    @Autowired
    private UserService userService;
    
    @PostMapping("/login")
    public String login(String username, String password) {
        User user = userService.login(username, password);
        if (user != null) {
            return "login success";
        } else {
            return "login failed";
        }
    }
}

7. 启动应用程序，访问http://localhost:8080/login进行测试

以上就是一个简单的Java Spring Boot + Mybatis + Oracle + Web实现登录功能的示例，希望对你有所帮助！
